Hi! I recently got two female guppies from a pet store. They were in a female only tank but I know they store sperm and there was a good chance they were pregnant. I’m just looking to confirm and also to know when they may give birth. The one with the yellow tail doesn’t seem as far along, but the other seems like she may be close. She has been doing a lot of shimmying, hiding, hanging near the heater. But I’m always so horrible at trying to identify the boxy shape.
